A New Monitoring System for Metal-Oxide Arresters

摘要

With effective resistance current as the detection method, this paper introduces a kind of distributed lightning arrester online detector design scheme, which is based on RS-485 bus and GPRS technology. It describes the design principle and detector signal acquisition, signal processing module design principle, signal communication and data wireless transmission, software design, etc. Detector realized the remote real-time monitor for the lightning arrester, safe and reliable.
